What’s the best way to control flies on a pig farm? It’ll depend - to some degree - on your farm's stocking density and layout. Also important: location, location, location. Some areas have a higher fly population than others.
An unregulated fly population can lead to herd illness and disease, impacting farm costs, production, and peace of mind. And with wafer-thin margins, controlling flies is essential for your herd health and productivity maximisation.
In this article, we’ll go over the best methods for controlling flies on a farm - to ensure they’re only a nuisance and not a problem. Ready to learn more?
Why Are Pig Units Affected by Flies?
As UK winters warm up and summer temperatures reach record highs, these new weather patterns support all stages of the fly development cycle from larvae to adulthood - posing an increasing problem for pig farmers.
What Types of Flies Affect Pig Farms?
1. Non-Biting Flies
Non-biting flies may not bite the pigs, but they can still transmit disease, acting as mechanical vectors for many pathogens spreading viruses, worms and diseases like salmonella.
2. Biting Flies
Biting flies feed on blood, and they can cause anemia and other health problems in some pigs.
A percentage of stock could have a hypersensitive reaction to the fly’s saliva, resulting in permanently irritated and painful skin. This reaction impacts meat production while also incurring large veterinary bills. No good all around.
What Problems Do Flies Cause on Pig Farms?
Flies irritate livestock, no doubt about it, but the main problem with flies is that they cause disease and may also transmit disease to other species. Yes, even humans. Indeed, flies have a big impact on animal welfare and productivity.
Flies cause prolonged and intense suffering to pigs through irritation and biting. Animals lose condition and don’t thrive. Production rates lower through loss of condition.
While flies may cause intense suffering for pigs through irritation and biting, they also demand valuable time, money, and patience in caring for sick animals. Losses - and further environmental pain points down the line - may become inevitable if you don’t prioritise a solution.
We’re here to help - and we’ve got a few solutions.

How To Control Flies in a Piglet-Rearing Area
Understanding the environment that flies crave can help pig farmers to create piglet-rearing areas which don’t entice them. A key component here is good ventilation - always a strong idea for healthy piglets.
Additionally, buildings and sheds can be treated before any piglets are introduced - with long-lasting products that continue to work safely whilst the piglets are present. It’s a win-win.
Flies are a year-round problem on a pig farm, so a fly prevention programme must be in place for the entire calendar year and site. If the flies are bad elsewhere on the farm, there’s a good chance a piglet-rearing station will become affected. Act preventatively!
Frequently Asked Questions
Are Fly Control Products Safe for Piglets?
It depends on the product. Glue-based and electrical fly traps are safe for piglets, providing they are placed well away from the pigsty. Piglets are curious creatures - and smart, too!
Farmers must use chemical products with discretion by following all manufacturer guidelines on dilution and quantities. Certain fly control products specifically aim at juvenile stock. If in doubt, check with your vet.
Some spray or fogging products are only suitable for empty buildings, with a recommended leave of absence before animals safely return.
Fly control is essential on any livestock farm, and pig units are no exception. Fly management creates a healthy environment - a holistic solution, if you will. More so, it helps optimise herd productivity and practises high animal welfare standards.You can rely on Dalton’s fly control products with a range of options designed for your farm’s needs. We offer a great money value and effective fly management - but especially, peace of mind. Check out our website and order today!
